Ignition Coil Driver Wiring Diagram
So the coil driver wire seems to be fine.
Ignition coil driver wiring diagram. The coils which are the basis for ignition coils and alternators have very specific electronic. 800 x 600 px source. It is very comparable in design to the pulse transformers used in other appliances such as fence chargers well suited for high voltage bursts. Compared with a a switched pwm drivers this simple linear laser diode driver provides cleaner drive current.
This video concentrates on coils from an electronic point of view and reading wiring diagrams. With the engine running i am getting a reading of 13 4 13 5 volts on every coil connector by disconnecting one connector at a time and probing the power feed wire. An ignition coil or spark coil is nothing more than a low frequency auto transformer with a relatively high turns ratio. The transformer typically has only a dozen or so turns on the primary but many thousands on the secondary.
I also include details of how i wired the circuit. Here is the schematic diagram of the circuit. This is my ignition coil driver using a 12v 40a car relay and including a 500v 22uf capacitor. Ignition coil distributor wiring diagram size.
